The effect of the material used and the pulp chamber extension depth on stress distribution of endocrowns: A three-dimensional finite element analysis

Aim: The aim of this study was to examine the effects materials used and depth extension into pulp chamber on stress distribution in mandibular molar endodontically treated teeth with endocrown restoration using three-dimensional (3D) finite element analysis (FEA). Methodology: Three-dimensional models were obtained at two different depths by taking a tomography root canal-treated tooth extracted for periodontal reasons: 2.5 mm (Model A) 3.5 B). Models divided following three groups according material type used: Vita Enamic (VE), Lava Ultimate (LU), IPS e.max CAD (EMX). aforementioned model further subgroups types cement NX3 MaxCem Elite Chroma (MX). Maximum principal (MPa) values under 600 N vertical load investigated evaluate effect design, type, cements distribution. Results: maximum observed EMX (13.000 MPa) MX group Model A, while lowest LU (5.932 A. areas highest both A B corresponding enamel margins. Conclusion: Materials higher elastic modulus show area surface, they transmit are lower. close dentin have more homogeneous distributions within restoration.
